IMPROVEMENT IN MACHINE FOR MAKING BARRELS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom. it may concern:

made certain new and useful Improvements in Mischines for Making Barrels, Oasks, and similar vessels; f

and I do hereby declare that the following is a full anl clear description thereof, reference being had to v the accompanying drawings, and to thc letters of reference marked thereon. My said machine receives the barrel, cask, tub, or

similar vessel, after the Astaves have been hooped to` get-her; and its object is to thereupon perform the several operations of cutting off or squaring the stave-ends, and of chamfering, howelling, and crozi'ng, all in one combined process.

And in the achievement of said object, the nature of this inventionl is in the arrangement of a rotating clamping-device, by whichthe barrel or cask is clamped, and slowly rotated, and in the combination herewith of one ortwo cutter-zu'bors, airangedfor lateral feed, and rotating rapidly, and carrying the several tools for cutting, chamfering, howelling, and crozing, all of which will hereinafter more fully appear.

To enable those skilled in the coopers arts to make and use my said `improvements, I will now fully describe the construction and operation thereof, having reference to the accompanying- Figure l as a general plan; to

Figure 2 as a longitudinal sectional elevation; to

Figure 3 as a transverse sectional elevation of said machine; and to Figures 4 and 5 as detail elevations and plan, re spectively, of the'cutter-head and its tools.

I support the operating-parts of my said machine on a proper base or frame, A, usually made of 'woodor east-iron.

On the upper edge of A said frame A, I arrange the slides A1, having ^ridges, or other projections, to form a lateral guide, and also a rolling-surface for the tables B.

. I Aprefer to arrange said tables ,with wheels b, grooved to t 4the V-shaped slides A1, but the same may rest by simple depending runners on saidslides. Said tables B are supported directly upon the axles of said wheels b, by hearings arranged-in the usual manner.

On said tables B, I arrange the clamping-devices,D as well as the arbors bearings.

In the ordinary application of mysaid machine for making barrels or casks, the processes heretofore described are performed-simultaneously for bothends of the barrel or eask, and I therefore arrange on each table the clamping-devices, and cutters and supports, mw to be described.

I support the clamping-device C, by its frame, onA

the inner end of the table B.

Said frame forms, by its inner surface, a cylindrical bearing for the geared clamping-ring Cl. Said ring has its inner surface -shaped conically, conforming to the exterior surface of the barrel or cask here to be entered.

In order to retain the ring C1 in its frame, and permit the rotation thereof, the pins or set-screws c are passed through the exterior frame C, and reach into a groove, c, of the said ling O1.

lf smaller sizes of barrels or casksare used, I place within the ring C1 a second ring, fitting, by its exterior surface, to the ring C1, and having its interior surface corresponding to the gauge of barrel or Cask; Simple set-screws may be used to retain the second ring in its place, the' pressure against it, in clamping the bau, rel, acting also to keep it in position.

In the operation of said clamping-device, it is necessary to move the same to a jamb upon the barrel or cask, and after completion of the operation to be per. formed thereon, vto withdraw said clamping-device. This I accomplish as follows:

The' clamping-device C, and its frame-yoke, being supported on andl attached to the table B, I arrange each table for longitudinal motion, operating the same by the shaft D, which is held at the pillowjblock D, to prevent end-play thereof. 1

On said shaft are arranged right and left screwthreads, engaging in nuts d, secured on each table B.

Inorder'to rotate the shaft D, and thus, by action of the screw-threads, draw up the nuts d and tables B, as required, I arrange on said shaft the gear-wheels d', communicating with vthe Wheel di of the countershaft D2, lying transversely across the frame A, and being supported thereon. I

Said shaft D2 is rotated by the hand-wheel D3.

In the usual construction of my machine, I make wheel D large and heavy, so that by a sudden application of the power ofthe opera-tor, it may be quickly turned, and thus act to throw the tables B and yoke C forward, and clamp the barrel or cask tightly.

In order to turn the barrel in the clamping-frame, I have arranged, in engagement with the geared clamping-ring G1, the spur-wheel G3, supported by the shaft C, upon standards on the tables B.

The shaft G4 is driven by pulley ,05, connected by belt With the exterior power-source. A

The pulley and shaft are here allowed to turn, but prevented from lateral movement by fixed guides, connected with the main frame A. The supportingstandards and wheels O3 therefore move on said shaft C, during thestroke of the tables B in clamping; and the feather, holding the spur-wheel 03 on the shaft C", slides in a longitudinal slot of said shaft.

In order` to arrange the outter-to`ols forpropcr operation of the barrel thus held and rotated, I have supported the cntter-arbois E by sliding bearings F,

on the slides F of the tables B. The bearings F are nicely fitted, to givera true rectilinear motion, and arranged with brasses and set-screws, at'bearing surfaces, in the usual Workmanlike manner.

The arbors E are revolved by pulley E, with beltcounection to the exterior power-source; and to feed the tool up to the stullof the barrel, keg, or cask, I have constructed a hand or power tbedirrg-de\-'ice,`as follows: v

A bar, G, extends longitudinally across, connecting the two bearings 11, and being secured thereto by a staple, g.

Said bar G has centrally placed thereon the nut G, in engagement with the screw-shaft H, this being operated by hand, wheel, or pulley. n

In the longitudinal reciprocal motion for clamping and unclamping, in which the bearings F are carried along with the tables B, the bearings F will simply move along the bar G; but in the feed-motion of the tool requin-ed, the bar G being moved laterally by the screw-shaft H, the bearings F and arbors E are moved laterally by said bar, thus giving the feed required.

Owing to the combined process here performed, the cutter-head is arranged in a peculiar manner to receive the several tools thereon.

Said cutter-dread (as indicated in figs. 4and 5) con srsts of a metallic socket-disk, I, varranged to tit upon the arbor-end, being pressed tightly against the shoulder' e by set-screw. l g c The saws I, for cutting otf the staveends, rnay be -cither connected with thedisk I, or be placed directly upon the arbor E, being-,then between the disk I Aand shoulder c.

Said saw is arranged with a slot, 1', for the ebamfering-tool P, this being held, by a proper set-screw, in a groove of the disk I. l

On the circumference 'of the disk I, the lrowelling- A tool I3 will be supported, being secured by set-screws.

Under said tool,l a proper groove, il, iseut in the disk I, to allow the cuttings to clear the ltool in work- Lastly, I secure, in a slot of the disk I, so aste project beyond its circumference, the crozirrg or groovingtool I4, also by set-screws or key, in proper manner.

The. tools thus prepared, being secured on the ar.- bors E, and revolving rapidly, are moved by the feeddevices G and H up to the barrel or cask, which slowly revolves in the clamping-ring Cl, and thus, by the lateral feed of the tools and the rotation of the casks, the

entire endof the barrel or cask is properly operated.

upon; and by the duplicate arrangement of arbors E, clamping-devices C, and tables B, both ends are finished at one operation.

Having thus fully described my invention,

1. The shaft O4, arranged with a sliding gear-wheel, C, to rotate the ring C, when the latter is in yokes C, and arranged for a simultaneous movement upon tables B B, substantially as set forth.

2. The arrangement of the shaft H, operating the bar G, bearings F, and arbors E, the latter' adapted to carry a. cutter-disk, substantially as set forth.

In testimony of said invention, I have hereunto set rny hand.

WM. BROWN.
